UNITED STATES ROMEO A. CASAROTTI, OF OAKLAND, CALIFORNIA.

BALL coox.

. Application filed April 24, 1924. Serial No. 708,675.

To all whom it may concern:

Be it known that I, ROMEO A. CASAROTTI, a citizen of the United States. residing at 7 Oakland, county of Alameda, State of California, have invented certain new and useful Improvements in Ball. Cocks; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings. and to the characters of referencemarked thereon which form a part of this application.

This invention relates to improvements in float-controlled ball cocks of the type par ticularly adapted 'to control the flow of water into tanks, such as those used in connection with water closets.

'One of the objects of this invention is to construct the barrel member of the cock in such a manner that the water flowing into the tank will always enter the same at the bottom and will never have any tendency to force its way past the valve or plunger to the top of the. barrel. This allows the use of a loose or free fitting plunger, and eliminatesthe need of a" leather washer as generally used to prevent the water from spattering over the top of the barrel. If the washer fits snugly, as it must toefliciently serve its purpose, there is grave danger of the plunger sticking sooner 01' later.

Further, my form of barrel enables the plunger and adjacent parts being viewed without taking the same apart, so it is very easyto make inspection for wear, etc. 7

Another object of the'invention is to provide a refill arrangement-so constructed that the refill tube is removed with the plunger as a unit and replaced in the same way.

This'eliminates the need of removing the refill tube by itself as is usual, when repairs to other parts of the mechanism in the tank must be made, and which usually necessitates bending the tube, frequently resulting in: its breaking.

. A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Fig. 1 is a sectional elevation of the cock. Fig. 2 is a cross section on the line 2-2 of Fig. 1. I i

deferring now more particularly to the characters of reference on the drawings, the

numeral 1 denotes a tubular member, of. such form that it may be removably mounted in the bottom of a tank 2 by suitable and ordinary means, and projecting a certain distance both into and below the tank. This member is adapted to be connected at its lower end to a water supply pipe by a slip-joint nut or coupling 3, or

other similarmeans.

From the upper end of the member 1 a plurality of vertical arms 4 extend upwardly, terminating at the upper ends in a sleeve 5 of a certain depth. Strengthening or bracing rings 6 connect the arms 4 at certain points in their length, the members 1, 4,5, and 6 being preferably formed as an integral casting.

' Projectingabove the sleeve 5 and located concentric therewith is a hollow head 7, provided at its lower end with a spider-like guide member 8 freely slidable in the sleeve 5; I i

The head 7 is connected to vertical link means 9 which is itself connected to one end of a lever or arm structure 10 itself pivoted freely slidable between and guided by the 1 arms 4. This head carries a valve member 15 of rubber or the like which, when the stem 12 is raised with the filling of the tank, seats against a flange 16 formed integral with the member. 1 and closes the water intake orifice 17 which said flange surrounds. Passages 18 are formed in the head 14 to the sides of the valve 15, said orifices communicating at their upper ends with the tube 13.

Removably mounted in the head 7' at an angle thereto and communicating with the interior of the same above the hollow tube 13 is a straight refill pipe 19.

It will therefore be seen that the necessary continuous refill passage is provided from above the top of the cock to the lower end thereof without the need of a solid tubular barrel.

It will also be seen that upon disconnecting the link 9, from the head 7, the latter.

. and all parts connected thereto, may be removed as a unit, without disconnecting any part thereof, and this unit may of course be similarly replaced.

The barrel being open throughout the water will naturally discharge into the tank at the level of the valve, there being no restrictions tending to cause the water to flow to the top of the barrel. This open barrel also permits inspection of the seating and condition of the valve without dissembling the parts.

From the foregoing description it will be readily seen that I have produced such a. device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims. I 7

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. A ball cock including a water intake member formed with a valve-seat, a plune geistructure slidably mounted for movement to and from the intake member, and having a valve to cooperate with the seat therein, and refill passage means provided as a unit with said plunger structure.

2. A ball cock including a water intake member formed with a valve seat, a plunger structure slidably mounted for movement to and from the intake member, and having a valve to cooperate with the seat therein, said plunger structure having passage means therethrough from end to end, and a refill-tube connected to the plunger to communicate with the passage means at the end thereof opposite to the valve.

3. A ball cock including a water intake member formed with a valve seat a floatoperatcd plunger structure slidably mounted for movement to and from the intake member, said structure including a head having a valve to engage the seat, a tube connected to said head, and another head to which the other end of the tube is connected, both heads having passage means leading from the exterior thereof to the tube.

at. A ball-cock including a water intake member formed with an upwardly facing valve-seat, aplunger structure vertically movable to and from the intake and having a valve on its lower end to cooperate with the intake-seat refill passage means incorporated with the plunger, and a plungercontrolling lever mechanism detachably connected to the plunger whereby on disconnecting the lever from the plunger the latter may be removed in an upward direction without disturbing any parts other than the lever mechanism.

5. A ball-cock including a water intake member formed with an upwardly facing valve-seat, a plunger structure vertically movable to and from the intake and having a valve on its lower end to cooperate with the intake-seat, refill passage means incor porated with the plunger, a plungerecontrolling lever mechanism normally connectedto the plunger,' and means whereby the latter may be removed in an upward direction without disturbing any part other than the lever.

In testimony whereof I affix my signature.

ROMEO A, OASAROTTI.
